Since we’re based in the Netherlands, I’m Dutch as well. So no language barriers here!
The Ventus W830 looks like a very impressive product, but I noticed it isn’t compatible with Homey. Does this mean we’d have to use an API to retrieve data from the device? I saw a discussion about this on the forum here: Ambient Weather Station Discussion.
The Shelly solution also sounds interesting, though I have to admit my technical knowledge stops there.
We’re planning to equip our warehouses with sensors (see: Airthings View Plus), but unfortunately they don’t offer an outdoor sensor option.
